Radiation leakage technique factors
The maximum rated peak tube potential is 84 kV and the maximum rated continuous tube
current is 3mAfor the maximum rated peak tube voltage.
Filtration
The Radiation port contains additional filtration of at least 2mm aluminum.
Total filtration min. 2.5mmAl.
When the X-ray beam is attenuated with the 3mmAl the resulting dose is 0.5 - 0.6 times the
original.
Maximum attenuation equivalent of the front panel of the
panoramic sensor head
0.5mmAl
Maximum attenuation equivalent of the front panel of the 3D /3Ds
sensor head
1.2mmAl
Rated line voltage
100 - 240 V~ ±10%
Maximum line current
Maximum 15 Amperes at 100 V~, 8A at 230 V~
Technique factors that constitute the maximum line current
condition
84 kV / 16 mA
Generator rating and duty cycle
1.5 kW, duty cycle approximately 1:10. The wait period is calculated using the following for-
mula:

where HS
MAX
= maximum tube anode heat storage capacity (28 kJ)
HS

= current tube anode heat storage
HS

= heat storage caused by next intended exposure (kV x mA x s)
f = tube anode cooling rate as a function of heat storage (given by tube
manufacturer)
Maximum deviation of peak tube potential from indicated value
±5%
Maximum deviation of tube current from indicated value
±10%
